I have 2 GeForce GTS 240 cards, on Windows 8 Pro with Media Center x64.They were previously both experiencing the CORE_OUTDATED loop, but a restart of the client has since resulted in the download/installation of the new core.

The current error I get, for both cards, is GPU_MEMTEST_ERROR.I believe they both are currently now looping, and continually getting the error, and failing tasks because of too many errors, and downloading new tasks to fail them too.These cards are stock Dell cards, and are not overclocked; I sincerely believe the error is erroneous.

The work server, information, and relevant logs, are below, for each slot.If you need anything else that can help you to solve this issue, please let me know in this thread.Regards,Jacob Klein

Here's another update. Joe has been working on this since around noon and sees the issues. We now think the memtest issue is due to an AS issue sending G80 clients to get work from non-G80 compatible servers. Your posts here were helpful to confirm this.

He's still working on the issue, hopefully with some fix in a day or so. This should also fix the ATI assignment issue.

When your client needs new work, it contacts the Assignment Server which starts a multi-step process that should give you work that your computer can process. Since you're getting the wrong kind of assignment, there must be something wrong with the AS.

Sifting through the posts in this thread and the CORE_OUTDATED thread it seems apparent to me that the problem lies in FahCore_15. It was the last and only thing that changed. If it were an issue with the WUs then all the G80+ video cards would probably be failing. However, even some 8800GT cards are happily crunching WUs which are failing on my G92 9600GSO.

I suspect the GPU_MEMTEST is an arbitrary check and subsequent rejection of any card with less than one GB of memory. Were it an actual check of the ratio of memory to GPU cores the one GB 9800GTX would fail worse than my 384MB to 96core 9600GSO. And it is my understanding (I could be wrong) that the video card memory is only used as a buffer to shuffle data to and from the processing cores rather than hold the entire work unit data set. Again, I could be wrong, but it would seem to be the logical way to handle the data.
